RTLO-xx718 Model Splitter Cylinder Assembly

LO Range or HI Range L - With the splitter control button in the "rearward" position, no air is supplied to the splitter cylinder cover top port (1). The constant air from the air filter/regulator assembly (2) moves the splitter piston forward, disengaging the rear auxiliary drive gear (3).

LO Range or HI Range H - With the splitter control button in the "forward" position, air is supplied to the splitter cylinder cover top port (1), moving the splitter piston rearward, engaging the rear auxiliary drive gear (2).

Insert Valve

The insert valve is a self-contained 1-13/16" valve assembly located in the intermediate shift cylinder cover. It cannot be disassembled except for the three (3) O-rings on the outer diameter. The O-rings provide a stationary seal and do not move in the cylinder.

Insert valve piston travel is only 1/32". When no air is applied to the valve piston top side, constant air supplied from the air filter/ regulator passes freely through the insert valve and to the cylinder piston backside, moving the yoke bar forward to disengage the rear auxiliary drive gear (LO range and HI range L).

No air on Signal Line

To piston backside, yoke bar forward Constant Air

When air is applied to the valve piston top side through the signal line, the piston moves down to cut off air supplied to the cylinder piston backside. This air is exhausted out the cover bottom port as constant air supplied from the regulator is directed to the cylinder piston front side, moving the yoke bar rearward to engage the rear auxiliary drive gear (LO range and HI range H).

Air on Signal Line

From piston back side, yoke bar rearward
